Figure 3From: Design of dual-diameter nanoholes for efficient solar-light harvestingDNHs optimization. (a) Maximized ultimate efficiency of the DNHs as a function of lattice constant a with Ltop/L = 50%. (b) Ultimate efficiency versus Ltop/L at a = 700 nm, dtop/a = 0.9, and dbot/a = 0.5.Back to article page
